You can unsend messages, whether it was to a single person or a group of people. The tool isn’t foolproof though, as recipients will still get an alert letting them know you deleted it.

The feature is part of the latest version of the Messenger app on iOS and Android, Facebook said Tuesday.

Facebook began working on the unsend feature last April after it was reported that a number of Zuckerberg’s old Facebook messages had mysteriously disappeared from the recipients’ inboxes years after the fact.

Later the company apologized for only making the feature available to its executives, and said it would bring the feature to all Messenger users before it deleted any more of its executives’ messages.
